SEWER WE'LL AND GRATE.

SPECIFICATION forming part of Letters Patent No. 490,301, dated January24, 1893. Application filed May 13, 1892. Serial No. 432.937. (Nomodel.)

To all whom it may concern:

Be it known that 1, Common. MUNSON, of Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Sewer Wells and Grates; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference beinghad to the accompanying drawings, and to theletters and numerals of reference marked thereon, which form part ofthis specification.

My invention relates to an improvement in sewer wells and grates.

It is among the objects of my invention to provide a sewer well indetachable sections which facilitates the manufacturing and handling ofthe sections and provided with locks for securely uniting the sections.

It further consists of and provides for a sewer well and grate which isparticularly intended to be placed in the curb of a street and allowthesewage to pass through suitable openings in the vertical side andhorizontal top of a portion of the well. The parts are also adjustableto fit the upper or grate portion of the sewer to make it register withthe curb line of the street.

In the drawings which accompany and form a part of this specification,and in which similar letters and numerals of reference refer tocorresponding parts in the several figures, Figure 1 shows partially inelevation and partially in vertical sections, my improved sewer well andgrate. Fig. 2, shows a plan view of the sewer well and grate adapted inform to be placed in a curved curb. Fig. 2 shows in perspective the wellshown in Fig. 2. Fig. 3, shows a plan view of the grate and well placedin a straight curb. Fig. 3, shows in perspective the grate and portionof well shown in Fig. 3. Fig. 4, shows locking projeciions provided onsections of the well for securely locking the sections together. Fig.5,.shows the same part shown in Fig. 4, placed together preparatory tolockin g. Fig. 6, shows the locks completely locked together. Fig.7,showsa plan view of a portion of the horizontal portion of the grate inconnection with a section of the well taken on line AB, of Fig. 1.

The well, 1, consists of a bottom section 1,

so far as the curb section 6 extends.

a middle section 1 and top section 1. If the height will permit two ormore middle sections, as 1 may be used. The sections are circular inform and cast with a flange as a adapted to embrace the next section. Onthe sections are also provided locking pieces 2 and 3, which consist ofaprojecting rib 2 on the inside of the casing and a stop adapted toengage the end of the projection and cause the projections 2 to registerwith each other when in looking position. The lock piece 3 is similar inshape to 2. The upper section of well is provided with an inwardlyprojecting rim as 4, on which is adapted to rest the horizontal portion5 of grate. Above grate 5,is provided a curb section 6, which is of asize and shape adapted to cover that portion of the well inside of thecurb line of the street. In the curb face of section 6, is provided anopening with a suitable grate as 7. The curb section 6, is provided withan overhanging flange 8, adapted to surround the upper section I of thewell On the inside of the curb section 6, is provided a downwardlyextending lug 9, which engages the rear side of grate 5, and holds thesame in correct position in the upper end of the well. It will beobserved that the grate 5 and the curb section 6, are so arranged thatthey may be turned to any desired position on the upper end of the wellto correspond with the curb line of the street. In Figs. 1 and 2, thecurb line is indicated by m. In the upper end of the curb section andresting on a suitable inwardly extending flange is a removable plate orcover 10, through which access may be had to the interior of the sewerwell.

In setting up the well the bottom section 1 is placed in shape andconnected with the sewer, and by reason of the well being in sections,easy access is had for the purpose of attaching or connecting it withthe sewer. The sections 1" and 1 are then successively placed upon thebottom section and by rotating the sections, the locking projections 2and 3, will be brought into engagements which firmly secures thesections together and prevents displacement. Grate 5 and curb section 6,are then placed in position and rotating brings the curb line of thecurb section so as to register with the curb line of the street.

It will be understood that the grate 5, is to be placed on line with orslightly below the gutter of the street, the grate 5, formingessentially a portion of the gutter. It will also be observed that theinner side of grate 5, terminates substantially at the curb line leavingthe remaining portion of the sewer well open and free, whichconstruction it is claimed will receive the sewage without becomingclogged with obstruction in better shape than where the grate extendsfrom the gutter line upon the vertical side of the curb.

What I claim as new and desire to secure by Letters Patent is:

1. The combination of a circular sewer well, and a curb section having avertical grated curb face, spanning the circle of the well and the curbsect-ion being of a form whereby a portion of the top of the well isexposed and a part is covered by the section, the curb section beingrotatable on and independent of the well, to enable the curb face of thecurb section to conform to the curb line of the street without referenceto the well, substantially as set forth.

2. The combination of a circular sewer well having a grate supportingrib, a gutter grate partially covering the top of the well and restingon the rib, and a curb section having a vertical grated curb facespanning the circle of the well and the curb section being of a form asshown, whereby a portion of the top of the well is exposed and a part iscovered by the section and having projections projecting adjacent to thegrate supporting rib and adapted to engage and retain the gutter gratein position, the curb section being rotatable on and independent of thewell, whereby the curb face of the curb section and the gutter grate maybe made to conform to the curb line of the street, substantially as setforth.

In witness whereof I have affixed my signa ture in presence of twowitnesses.

OOUNTCIL MUN SON.
